Abstract
Metal complexes of the formula I or I' [LDH]M[L](I) [LTH](M[L])(I1) wherein n is an integer 1 or 2, m and p each is an integer 1 or 2, the sum (n+m) being 2 or 3, M is a metal with an atomic weight of greater than 40 such as Iridium, L is a ligand as described in claim, and LDH is a bidentate ligand of the formula I1 and LTH is a dimer of LDH, binding to 2 metal atoms M, of the formula II′ wherein W is selected from O, S, NR, CRR, X is N or CR, Y is selected from O, S, NR; and further residues are as defined in claim, show good light emitting efficiency in electroluminescent applications.
